B2B Profile // Parapet Wall protection systems
Aluminium Cappings & Wall Coping
Architectural wall cappings, parapet coping systems, and metal wall capping profiles. Fabricated to your exact widths from marine-grade alloy. Snap-on secret fix brackets, Qualicoat PPC finishes.
A CAPPING THAT DOES NOT COVER THE FULL REVEAL LETS WATER IN. WATER IN MEANS CALL-BACK. CALL-BACK MEANS MARGIN GONE.
// Definitions
What Are Aluminium Cappings and Parapet Coping Systems?
An **aluminium capping** (also known as a wall coping or metal capping) is a precision-formed protective profile installed over parapet walls, window heads, wall boundaries, and EWI reveal edges to prevent rain penetration. Fabricated from marine-grade alloy, these made-to-measure cappings provide a seamless, corrosion-proof, and lightweight boundary seal. They allow for natural thermal expansion while ensuring that rainwater is shed clear of render systems, preventing staining, dampness, and structural cracking.

Capping Configurations
Window Head Cappings
Protective head cills and drip-edge profiles installed above external window openings, throwing water clear of glazing seals.
Compatible with Knauf and SolTherm EWI render margins.
Configure Profile →
Parapet Wall Cappings
Secret-fix coping cappings for flat parapet walls. Sliding joint splices allow silent expansion without breaking seal integrity.
Compatible with concrete blocks and structural steel decks.
Configure Profile →EWI Reveal Cappings
Extra-wide cappings specifically folded to seal top margins on external wall insulation facades.
Compatible with Baumit and Rockwool facade render coatings.

Custom Profile Cappings
Bespoke return bends, splayed angles, and corner profiles built from CAD details for irregular masonry structures.
Compatible with ICF walls and non-standard architectural projections.

Professional Site Measurement & Installation
Avoid callback errors and measurements mistakes. We provide a complete site survey, measurement service, and professional fitting across Dublin and Leinster. Our technical engineers will visit your site, capture the exact reveal dimensions with 3D scanning or laser precision, and install the finished cills, cappings, or copings.
// System Interface
Every system has a different reveal depth. We fabricate to your exact spec.
Our profiles conform directly to dimensions required by Irish cladding and facade system specifiers:

Standard Cappings vs. Made to Measure
Standard Off-the-Shelf
- ❌ Fixed projection depths leaves EWI reveals unprotected.
- ❌ Mill-finish limits matching facades or RAL frames.
- ❌ Rough onsite cuts cause rust and callback snags.
- ❌ Leakage at joints drains straight into the wall insulation core.
Fabricator.ie Made-to-Measure
- ✅ Custom depth options up to 600mm to seal thick EPS reveals.
- ✅ In-house Qualicoat PPC matching window framework codes.
- ✅ Pre-formed welded corners and internal expansion splice brackets.
- ✅ 0% error record using app-based site measurement verifications.

Frequently Asked Questions
What aluminium cappings are compatible with Baumit EWI systems?
We fabricate custom aluminium cappings that interface precisely with Baumit systems. Our profiles accommodate varying reveal depths, providing a secure, watertight seal over insulation boundaries and preventing render cracking.
What is the difference between a capping and a flashing?
A capping (or coping) sits directly on top of structural boundary elements like parapet walls, window heads, and wall boundaries, sealing them against water. A flashing is a thinner, flexible profile installed at junctions, wall valleys, and roof intersections to shed running water clear of joints.
Do you supply aluminium cappings outside Dublin?
Yes. We supply custom made-to-measure aluminium cappings to builders and EWI contractors across all 32 counties of Ireland, with secure delivery to sites and yards.
Can aluminium cappings be powder coated to a RAL colour?
Yes. All cappings are powder coated in-house using architectural-grade Polyester Powder Coating (PPC) certified to Qualicoat standards, matching window frame or cladding RAL codes.
